Well, I bought without a trial and now I think trials are absolutely essential for the Blue and Orange as the user has to see if these first creations feel ok without any of the improvements others Aquas have received.

That being said I'd encourage to target an update for the Blue eq!

The gui/ergonomics/ dialaction (too jumpy and jerky) and are just no good compared with the Acquas that followed and I own .
The gui is too tiny, a real strain on the eye (to see the khz from 1m back) and the bypass button doesn't seem to have a 'led' to mirror its state.
I spend to much time on how the dials react when touching them to check what happened.

The manual seems to have the mid and high graphs mixed up
see attached screenshots

All in all I would bring this up to the ergonomics that users have come to appreciate when working with updated Aquas.
AA Acqua users have confidence that if something wasn't perfect in previous build it will be ironed out with the next core update.
So why break this 'rule' with the two plug ins that in a way meant the foundation and the breakthrough for AA and its introduction of Acquas?
An updated and probably also resampled Blue and Orange (as I have the feeling something could be improved soundwise as well) would make the Acqua line ideology consistent imho.

I buy Acquas with the same motivation as e.g. RME converters with their steadily improved Total Mix software and great drivers: it feels like a futureproof investment.
